|  * | |
|  * \ingroup group__application_layer_interface__inserters | |
|  * | |
|  * This class converts a pointer variable into a string, thereby enabling it to be | |
|  * inserted into a logging statement. Consider the following statement | |
|  * | |
|  * \code | |
|   void*       p   = reinterpret_cast<void*>(0x01234567); | |
|   char        s[] = "abc"; | |
|   std::string str("def"); | |
|  | |
|   pantheios::log(pantheios::notice, "s=", s, ", p=", pantheios::pointer(p, 8, pantheios::fmt::fullHex), ", str=", str); | |
|  * \endcode | |
|  * | |
|  * This will produce the output: | |
|  * | |
|  *     <b>s=abc, p=0x01234567, str=def</b> | |
